What Is It and When Do You Need It?

Times are written in many forms, as a long count of seconds in a log file, or as hours and minutes on a time sheet. This tool moves between all of them.

Type seconds, minutes or hours, or a time with colons.

How to Use This Tool

  1. Enter or paste your input in the box or boxes above.
  2. Choose the options, if there are any.
  3. Press the button to run the tool.
  4. Read the result and use the copy button where one is shown.

How the Calculation Works

A plain number is multiplied into seconds using the unit you chose. A time with colons is read from the right: seconds, then minutes, then hours. The total seconds are then broken into hours, minutes and seconds with whole-number division, and also shown as total minutes, decimal hours and words.

Worked Example

3661 seconds is 1:01:01. 1:30:45 is 5445 seconds, 90.75 minutes and 1.5125 hours.

Tips and Common Mistakes

  • More than 24 hours is fine; days are shown too.
  • Negative values keep their sign.
  • Check the first result against a case you already know, so you can trust the tool for the rest.
  • Nothing you type leaves your device. The work is done by your browser, so it also works with a slow connection once the page has loaded.

Next, you may need the decimal hours converter, time duration calculator, day of the week calculator, date difference calculator.

Everything runs in your browser. Nothing you type is uploaded, stored or sent to any outside service.
